I'm trying to fetch all the tasks that have been completed by me, irrespective of whether they have been assigned to me. Right now I'm pulling all the tasks that are assigned to me and completed by me using - 'https://app.asana.com/api/1.0/'tasks?assignee=me&workspace=' + workspaceId +'&completed_since=' + date + '&opt_fields=completed,name,completed_at' ;
Then adding a filter to check if completed is true.
